In California, the race for lithium is on with a number of companies setting up on the edge of Salton Sea Lake.
They are looking to find the most effective and environmentally friendly way to extract this precious metal used in rechargeable batteries.
Up to now, most of the lithium in the US has been imported.
One company is hoping to change this by drilling a 2,300 metre deep well to extract the metal.
Jim Turner is the chief operating officer of Controlled Thermal Resources.
As countries move away from the use of fossil fuels and turn towards electric vehicles, demand for lithium is predicted to double by the end of the decade.
The Salton Sea Lake used to be a popular leisure destination attracting Hollywood celebrities and boat racing fans.
However, the lake and its ecosystem have begun to evaporate due to climate change.
This has seen toxic dust released causing the highest rates of respiratory illness in the country.
Charles Diamond is part of a team of researchers that regularly conducts tests at the lake to ensure that the activities around lithium extraction do not further exacerbate the situation.
